physical pushbutton on the device or a button on a page of the device’s wireless

network configuration menus.

Congratulations! You should now have a secure connection between your Cable

Modem/Router and a device. Now is a good time to check that your device’s Internet

connection is working. Open your browser and go to a familiar Web site. If you are

able to connect, continue with the next step below.

If you are not able to connect to the Internet, please see

Appendix A:

Troubleshooting Tips

.

If you have other devices whose WPS security you need to set, repeat steps 1

through 3 for each device. When they are finished, the basic setup for these local

wireless devices should be complete

.

Connecting Additional Computers and/or Other Devices to the

Cable Modem/Router’s Ethernet/LAN ports

You can plug up to four computers, game consoles, or other Ethernet-capable devices into the

Cable Modem/Router’s LAN ports. For information about your specific device, please refer

to the documentation that came with that device. Follow the instructions below for each

computer or other device.

1

If you connected the Cable Modem/Router to a computer using a wired connection

when setting up the Cable Modem/Router, unplug the computer now if you don’t

want that computer to stay connected to the Cable Modem/Router.

2

To connect a computer or other Ethernet-capable device, plug one end of an

Ethernet cable into an available Ethernet (LAN 1, 2, 3, or 4) port on the Cable

Modem/Router and plug the other end of the Ethernet cable into the Ethernet port of

the additional device you want to connect to the Cable Modem/Router. (If you are

connecting a hub or a switch, this is typically called an Uplink or Expansion port.)

If

you are connecting a computer or game station, go to step 5 of this section.

3

If you are connecting a network device such as a switching hub, use the instructions

that came with that device. Then reboot any computer that is part of your network.

For example, if you connected a switching hub, reboot any computer that will be

connected to that switching hub.

4

If you are connecting a HomePlug adapter pair with one adapter plugged into the

Cable Modem/Router and an AC outlet, and the other adapter plugged into a

computer, game station, or other device and an AC outlet, make those connections

and then go to step 5.

5

Verify that your Internet connection is working. Open a Web browser on each

computer that’s using your network and try to connect to a familiar Web address.

26

6

Congratulations! You have connected an additional device to the Internet. You can

connect up to 4 Ethernet-capable devices to the Cable Modem/Router, following the

instructions above for each device by starting at step 2 of this section.

Changing the Default Wireless Settings

Your Cable Modem/Router comes from the factory with a default SSID (Wireless

Network Name),

WPA-PSK/WPA2-PSK

wireless security and a random Wireless

Security Key (Wireless Password). These default settings for your router are listed on the

label of your unit. When the cable modem is standing vertically this label is located on the

side of your modem

.

Most should use the default settings.

You may want to change your wireless settings if the wireless devices on your network

are already configured to use an existing wireless network name and password. Instead

of having to reconfigure all the devices on your network, you can change the Cable

Modem/Router to match the existing settings used by your devices. Read this chapter if

you want to use another wireless security mode, or if you want to change either the SSID

or Wireless Security Key. If you want to use the default wireless settings, you can skip

this chapter.

About Wireless Security

There are two basic wireless security modes, WPA and WEP. There are two versions of

WPA: WPA and WPA2. When configured as part of a typical home or small office

network, WPA and WPA2 require a Pre-Shared Key, or PSK. These modes are typically

called WPA-PSK and WPA2-PSK, respectively, though sometimes they’re just called

WPA and WPA2. You can enable either WPA-PSK or WPA2-PSK alone, or you can

enable both WPA-PSK and WPA2-PSK together. By default, your Cable Modem/Router

has both WPA-PSK and WPA2-PSK enabled. You will only need to change the security

mode if you know that you have a device you are connecting to your wireless network

that only supports WEP. (Go to

Setting Up Security Using WEP

.) In the unlikely event

that you want an unsecured network, this is discussed late in this chapter in

Disabling

Security

.

Note:

If you have a Radius Server (very unlikely for a home network), select the

WPA/WPA2 options without PSK. All instances of WPA and/or WPA2 that follow refer to

WPA-PSK and/or WPA2-PSK unless noted otherwise.

28

You can check to see if all other clients that you plan to put on the network support WPA

or WPA2. You can do this by checking the manual that came with each device or by

checking the configuration software for the installed device. Look under

Security

or

Encryption

or

Setup

or

Advanced Features

. Most devices will support one of these

modes.

•

To change the Wireless Network Name (SSID) or Wireless Security

Key/Password (Pre-Shared key) used by your Cable Modem/Router go to

Changing your Wireless Network Name(SSID) and Pre-Shared Key

.

•

If any of the devices you want to connect to your wireless network do not support

WPA or WPA2, go to

Setting Up Security Using WEP

.

•

If you need to set up an unsecured network, see

Disabling Security

.

Changing your Wireless Network Name(SSID) and Wireless

Security Key/Password

Most likely your previous wireless network used 2.4GHz. If you want to change your

Cable Modem/Router settings to match your existing network settings follow the steps

below.

If you have devices that support 5GHz then you should connect to the Cable

Modem/Router’s 5G network. For instructions on connecting to the 5G network refer to

Chapter 3, Connecting other Devices to the Cable Modem/Router

.

To check if your device supports the 5 GHz, you can scan for available wireless networks

on your device.

If you see a wireless network named

Zoomxxxx-5G

than your devices

supports 5 GHz and you should follow the instructions for connecting that device to the

Cable Modem/Router found in Chapter 3. If you only see

Zoomxxxx

then your device

does not support 5 GHz. In both cases, xxxx are the last 4 digits of the CM MAC address.

You can find

Zoomxxxx

printed on the label of your Cable Modem/Router. When the

cable modem is standing vertically this label is located on the side of your modem.

Click

Wireless

on the top menu.

4

The Wireless Radio page appears. Under Select 2.4 or 5 GHz option. Select 2.4 GHz

if your existing wireless network used 802.11n 2.4GHz. If your existing network used

802.11n 5GHz or you just want to change the SSID for the 5 GHz network select 5

GHz. Click Apply.

5

To change the wireless security, start by setting all the following drop-down menus to

Disable: WPA, WPA-PSK, WPA2, and WPA2-PSK.

6

Then select Enable for the mode(s) you choose for setting wireless security.

Note:

To use WPA2 /WPA,

all

of the wireless devices on your network must support

either encryption method. In this case, enable:

o

WPA-PSK and WPA2-PSK (if you want to use a Pre-Shared Key)

or

o

WPA and WPA2 (use this only if your network uses a Radius Server. This

is very uncommon for a home network)

If you know that all your devices support the more secure WPA2 you can enable

WPA2 only (or WPA2-PSK if you want to use a Pre-Shared Key) instead of WPA and

WPA2.

7

In the

WPA Pre-Shared Key

text box (only if you selected an option requiring a

Pre-Shared Key), enter a passphrase of your choice (a minimum of 8 characters).

Write down this passphrase and put it where you can find it – on the bottom of the

Cable Modem/Router case, for instance.

8

Click

Apply

.

9

Now you need to set up each of your wireless devices with the SSID and passphrase

.

See

Chapter 3, Connecting other Devices to the Cable Modem/Router

for help on

connecting your wireless computers and devices.

Your security setup configuration is now complete!

Setting Up Security Using WEP

WEP is an older wireless security standard that has been shown to be easily defeated.

Because of this, the use of WEP has been phased out of use by the wireless industry and

should only be used if

any

when one of your network devices DOES NOT support WPA

or WPA2.

WEP can be configured two ways: 64-bit and 128-bit. 128-bit WEP provides

more security than 64-bit.
